work.

When I use the designation plate 1 .I do so in a broadsense to include .notonly a plate "made of glass, but made "of other materials which. are sensitized foruse-in photographic- The package is'anarticle of manufacture: for it can be soldto thetrade for use b cona sensitive plate and this late is so related with what might be'consi ered the envelop that light rays cannot accidentally strike the plate." The package, however, ordinarily includes in its'make-up aslide and when the package itself is placed in a camera box this slide is-withdrawn to expose the plate and when the exposure is made the slide can be moved to its ori inal position to .cover the plate, aftcr whic the package can be re-' moved from the, camera box, subsequent to which the plate can be removed from the .package'forgdeveloping, while the envelop can be .destroyedf The invention includes certainbroad re lations which will succeed the following de scri tion, in which latter I will definitely descri e the form of embodiment of theinvention illustrated in the drawin s, such description being for the purpose 0 enabling those skilled in the art to practice the invention, Referringto the drawings, Figured is a front view of a package including my invention."

f-si se. I prefer: to make the envelop of ,aper. '.;The paperamay be thin or thick. some cases the paper will be as heavy as pasteboardfor strawboard. From tliis it will be, obvious that I .use the'term paper in a general way to include -not only the sub stance thusfamiliarly known but other material suitable'for making an envelop involving my invention.

The envelop is generally made of a shape to correspond with that of the plate and that shown in the drawings includes in its-construction a backing. sheet as 1 which in area.

is the same as that of the envelop. This sheet is preferably opaque to light rays and it may be-blackf I attach to the-inner face of the sheet 1 a; frame as 2 of paper and this frame is adapted .to inclose the sensitive plate 3. The frame 2 may be united to' the sheet 1 in any desirable way, for example, by paste or some other adhesive. The plate 3 may be attached to sheet 1 bysuch an-adhesive. Themarginal portion of the frame 2 coincides with the marginal portion of the sheet 1. To the frame 2 I may unite by glue or its equivalent the frame 4, the marginal portion of which registers with the marginal portion of the frame 2 and sheet 1. The ,sides and ends of the frame 4 are deeper than the corresponding portions of theframe 2 and said frame 4, as clearly seen-0n inspection of 2',='overlies the marginal portion of the plate 3. By the construction described, therefore, the plate is held firmly in place with the frame 4 overlying a small ortion of the sensitized surface of said pate. Themajor portion of the sensitized face of said plate is, therefore, exposed so far as the elemenwreviouslyspecifically described are concern Y is essential, that the sensitized surface 0 the plate should be covered, and as will hereinafter ,aiipear I provide a slide for this purpose. n addition to the frame 4 there is another frame as 5. I This frame 5 is shown as consisting of two sides and an end and said frame 5 is united with'the frame 4 in some suitable way, as for example in the manner hereinbefore described for uniting certain other parts, that is by glue. The edges at three sides of the frame 5. register with the edges at the corresponding sides of the sheet 1, frame 2 and frame 4,'the frame 5 being. open at the remaining side to receive the slide.

The slide (iis guided by the sides of said.

In the ordinary handling of the packa ef it 4 frame 5 and is of some opaque material or is of such a'character as to Vprevent light rays passing therethrough. closed or in, its inneror lower edge abuts against the transverse portion of the frame 5, as clearly shown inFig. 2. By removing the slide 6, the plate 3 may be exposed. There upper ends of the sides of said frame 5. The

' upper end flap 7 is, therefore, not attached extends over the upper edges of the sheet 1 and frames 2 and 4 to make a light excluding to anythiri so that when the slide 6 is withdrawn as 0 early shown in Fig. 4 this upper flap 7 can of itself spring into a recess or indentation 4' in the upper transverse portion, of the frame 4 so-as to exclude light 1n the.

opening left by the slide 6. B virtue of the connection of the frame 7 wit the frame 5 there is a bellows like effect produced which permits the ready insertion-of the slide 6 after an exposure. It will be understood that the frame 7 overlaps the'marginal portion of the slide 6 when the. latter is in and thatit holds said slide in position at such time. Said slide 6 may be equipped with suitable means such as a tab or' car as 9 to facilitate the withdrawal thereof andwhich extends outward from the outer edge of said slide; said outer edge has in addition to said tab, a flap 6 which when the slide is in closure at this place.

When the article of manufacture is put on the market it consists of an envelo and a plate, the plate being thoroughly 0 osed in,

ut being accessible for exposure when in a camerabox by the withdrawal of a slide.

When exposure is accomplished the slide can be closed and the packagecan be taken from the camera box, following which the plate can be easily removed from the envelop and if desired the latter may be destroyed.

What I claim is:

1. An article of manufacture havin a bacldsheet, a late-inclosin frame attac ed to said back s eet, a secon frame attached hen the slide is to the plate-inclosin frame, the inner portion of which exten s inwardly beyond the.

edges of the opening in the plate-inclosin frame, a third frame attached to the secon frame and having two opposite sides, and a slide ada ted to move between the'sides of said thir frame.

2. An article of manufacture having a back sheet, a late inclosin frame attached to said back s met, a secon frame attached to the plate inclosin frame, the inner portion of which'extends e ond the edges of the opening in the plate inc osir'ig frame, a' third frame consisting of sides and an end and at tached to the second frame, a slide ada ted and attached to the second fram'e,'. a-slideadapted to move between the sides ofsaid third frame, and a'fourth frame having inwardly folded marginal portions attached to the sides and end of the third frame.

4. An article of manufacture "having a back sheet,a plate inclosing frame against theback sheet, a secondframe against the plate inclosing frame, and the inner portion of whichextends beyond the edges of the opening of the-plate. inclosing frame, a third frame consisting of sides and an end and lying against the second frame, a fourth frame lying against the third frame and having inwardly folded sides and end flaps, said parts being suitably attached together, and a slide adapted'to move between the sides of'the third frame and having a light excluding iii testimony whereof I affix my signature to this specification, in the presence of two w1tnesses.- v
